5 reasons to get cavity wall insulation

June 15, 2017

Cavity wall insulation involves inserting an insulating material between the two layers of brick that make up a cavity wall, either at the time of building or as a retrofit measure. Clearly, it’s not a choice if you have solid walls, but for those who don’t it can be a really worthwhile – and affordable – option. Cavity wall insulation will make your home feel much warmer, and it has other benefits too. Here’s why we recommend installing it.

Cavity wall insulation is one of the cheapest energy saving measures you can install.

It can be really effective and bring great savings – so it has a bigger payback compared to other measures. Unlike some types of insulation, cavity wall insulation can’t be installed yourself, but it is also not that expensive to have installed. Insulating costs will vary depending on where in the country you are, but typically a flat or mid-terrace house costs between £3-400 and a detached house just over £700, with semi-detached houses and bungalows somewhere in the middle. Those on certain benefits are eligible for free cavity wall insulation.

Cavity wall insulation reduces your energy bills.

Cavity wall insulation can save you £100-200 a year on your heating bills. This means it typically pays for itself in as little as two years.

Cavity wall insulation reduces your carbon footprint.

If your home is one of the vast majority heated with gas or electricity, generating that energy involves burning fossil fuels, which has devastating consequences for the environment. If your heating is wasted leaking through walls, it means you’ll need to use more to keep up your required temperature. This means more demand for energy, and more generation needed. If we all had more efficient homes, the UK’s carbon usage would drop considerably.

Cavity wall insulation is quick and easy to install.

As home improvement measures go, it’s non-invasive and causes very little disruption to the household. All work is done from the outside of your external walls. An insulating material is injected into the wall through small holes drilled in the mortar joint of the wall. It can normally be done in two hours.
